Under normal circumstances, cerumen in infants does not need to be treated. In the case of cerumen embolism, the child will have symptoms such as earache, hearing loss, crying, irritability, etc., which should be dealt with promptly, as well as if there is already a skin infection of the external auditory canal. For very hard cerumen clusters, sodium bicarbonate ear drops should be applied to the ear 4-6 times a day for 2-3 days to soften the cerumen and then rinse the external ear canal or remove it with instruments. If the skin of the external auditory canal already has obvious secondary infection and the pain is severe, antibiotics should be applied first to control the acute infection, and then cerumen removal operation should be performed after the symptoms of infection are relieved. Antibiotics such as amoxicillin, azithromycin, cefaclor, etc. can mostly be used. It should be noted that the ear canals of infants and young children are narrow, so parents are not recommended to try to remove the cerumen by themselves, and should avoid removing the cerumen violently with an ear-digging spoon, and babies with cerumen embolism should consult a doctor promptly. In daily life, attention should also be paid to keep the baby’s external ear canal clean.
